Denis joined the lab in February 2014 and started work building up our nanowire sensing project. Later he took the lead on our scanning nano-SQUID efforts, establishing the fabrication and use of SQUID-on-tip sensors in our group. After 4 years in the group, he took a position at the Federal Institute of Metrology (METAS) in Bern, Switzerland. In early 2020, Denis moved to Nanosurf in Liestal, Switzerland.
